I had the portal set as index.php and the forum then became index.php?forum. I want to return the forum as index.php but folks have booksmarks that point to the index.php?forum. How can I redirect (rewrite?) the index.php?forum >>>index.php?
"forum" (which doesn't exist) is mapped to "index" (which does exist). So when some one visits "forum" it loads the index. And because "index" is canonicalized in XF it will actually redirect the URL to "index".
